<p>are new error codes always (highest number I can find in the codebase) + 1?</p>

<p><span class="user-mention" data-user-id="116883">@tmandry</span> I've also gotten the feeling there are also "groups" of a sort, i.e., we don't sequentially number - but +1 from the last one in a given error codes file I think is correct</p>
